Simply put, the density of clouds is different than the surrounding air. That's one reason why you could experience turbulence when you fly through a cloud. But another, and often more significant, reason turbulence occurs in clouds is due to the unstable mixing of air due to the temperature, pressure, and velocity changes within clouds compared to the outside air. The difference in these factors between an air parcel within vs.
Clouds can give you a signpost in the sky marking the location of turbulence and hazardous weather conditions. They can mark frontal passages, mountain wave activity, thermals, temperature inversions, and more. There are plenty of reasons why turbulence forms , but the severity of windshear is arguably the most critical factor. As you climb to cruise altitude, you'll fly through layers of air with different densities, wind speeds, and temperatures.
How the air mixes between layers determines if you'll feel turbulence or not. If the mixing is smooth and spread out over thousands of feet or even miles, you might not feel much turbulence at all and you may see the nose of the airplane gradually swing towards the direction of the prevailing wind.
If the shear area decreases in size or increases in velocity over a confined area of a few dozen or a few hundred feet, there's a recipe for incrementally stronger turbulence. Short shear areas generally create "chop" and longer shear areas generally create turbulence. You can think of the turbulence when entering a cloud deck the same way, as mild windshear.
Have you ever noticed that if you can outclimb a haze layer or fly just above the tops of scattered cumulus clouds that the ride is much more smooth? This is especially apparent in the summer and is sometimes caused by a temperature inversion, where a layer of warm air sits on top of cooler air below. Some people call this a "capping inversion" when you can physically see the "cap" of the haze layer around you.
Spending less on fuel is also great for airlines, for obvious reasons. So, flying too high can also cause problems. Plus, the higher a plane goes, the more fuel it has to burn in order to get there so there are some drawbacks with certain altitudes as well. Flying higher means planes can avoid birds usually , drones, and light aircraft and helicopters, which fly at lower altitudes.
According to Your Mileage May Vary , the direction in which your plane is traveling can also affect what altitude it will climb to. Planes flying eastward including northeast and southeast will fly at odd altitudes i. Routes going in the same direction are also often planned so that planes are 1, feet above or below each other to avoid a collision.
Thanks for being so respectful, Jake! Kiki Jan 8, Jan 9, Tess Feb 21, You are liars of the worst kind. These are not contrails, this is weather modification, geo engineering program. How dare you make light of it as kids are breathing it and dying. You are murdering people for the govt. You stink.
Feb 22, Yogesh Oct 29, I didn't know about this white tracks like why these plains are leaving this type of track N then I searched on Google N Wonderopolis you rally helped me in this topic Oct 31, You're very welcome, Yogesh! Dakota Jun 19, Jun 20, And if you were to say like some that was 2 lines would it go away before you finish. Nancy Jun 19, This is really cool the way they write massages in the air with a plane.
Hi, Nancy! We appreciate your comment! B Jun 19, I have never seen it be done before but it looks pretty. The work they do is awesome. Teiona M. Jun 19, I liked that you guys told us about why air planes leave trails.
Also how they leave letters with the air planes. Monet Gray Jun 19, I liked how you can write words in the sky with the planes. I also like when you make shapes that's really pretty. Once i went to a air show and it had people sky writing and it was really cool.
I would love if someone did that to me. That sounds like a lot of fun, Monet Gray! We bet you learned a lot! Anya A. Thats cool how people can purpose by skywriting. I didnt know that skywritting was way back to I saw a air show before its really cool.
Cole H Jun 19, I didnt know that the "special smoke" was made from the exhaust overheating and oil being sprayed on it. Pretty odd. Jun 21, S May 6, Funny because when I was younger and saw sky writing or airplane trails I always used to think that they were a special thing only for me and no one else. I don't know why that is just how my brain used to work, now reading this I am very interested!!!
Wonderopolis May 6, Ilma May 6, I never knew that airplane engine produces exhaust, just like the car do. I also didn't know that pilots have to learn different patterns and work on the smoking machines, and be able to write unique messages in the sky. It is also way different, how the skywriters use to do things in olden days than comparing to today.
Hung May 6, I never knew most of those facts until today. That was what i had to do for my homework. So I liked it. Great, Hung! I do believe the lines in the skies create magical sunsets and direct us to spiritual awakenings. Wonderopolis Apr 20, Earnest Hemingway Apr 1, Wonderopolis Apr 1, Ryan Jan 23, Let me begin by informing you that I work in the Aerospace Industry as an engineer.
Your article has some useful information. You are buying into the narrative. I'm not arguing that planes exhaust water vapor as a result of combustion, nor am I arguing that the water condensation will dissipate and fade away. There is science behind what you are saying, but I want you to do something. Look at our sky. Next time you are walking around the yard or into wal-mart or whatever and you see the plane actually leaving the so called "condensation trails", look around.
It is almost guaranteed that you will not only see one. These planes are spraying whatever they are spraying in a strategical pattern. Return to that same spot each hour over the course of hours.
These trails do not dissipate. These trails do not fade until many many hours after they should have. We have always just accepted this as "overcast" conditions. We have always just accepted the water vapor emission and condensation is what is being emitted from these planes. We as society do not pay attention anymore. And our government has definitely capitalized on this fact.
It was only recently that someone told me to do exactly what I am telling you and I now see it. With my own eyes. Best of luck, Cheers! Wonderopolis Jan 23, Ryan Jan 26, Wonderopolis Jan 26, Makani Jun 22, Debbie Dec 23, This also explains why you feel the plane slowing down during landing.
In most cases, these planes use a piston-powered engine, which operates similarly to the engine in your car and with power that only allows for shorter flights, according to the National Business Aviation Association. This type of engine prevents these smaller planes from reaching the same altitudes as commercial aircraft. Pilots also refrain from flying these types of planes at greater heights because of potential health risks like hypoxia, which is when tissues do not receive enough oxygen, according to the National Institutes of Health.
That lack of oxygen can occur at higher altitudes due to a decrease in oxygen pressure, according to the FAA. As the plane ascends, the level of oxygen decreases, which can cause rapid decompression for an aircraft that is not pressurized in the same way as a commercial airplane. What about helicopters? Choppers are mainly designed to fly short distances and typically fly much lower than airplanes, normally at under 10, feet.
